2. Grinding. First, wash the soybeans, soak them in clear water for one night, then grind them into slurry and filter the residue for later use.
3. Boil the pulp. After the ground raw soybean milk is cooked in a pot, 20%-25% water is added to reduce the concentration of soybean milk and slow down the speed of suspected solidification, so as to slow down the formation of protein solidified substance network and reduce the wrapping of water and soluble substances, so as to facilitate the smooth discharge of water during pressing.
4. Solidification. When the slurry temperature drops to 8_0_-90℃, the slurry can be ordered with brine. Pay attention to uniformity and consistency when ordering slurry, and stir frequently, but prevent disorderly stirring. Stop when sesame-sized particles appear in the pulp, cover it for about 30-40 minutes, and wrap it when the pulp temperature drops to about 70 ~ C.
5, stroke the brain. Chop the tofu before wrapping, which will not only help to break the network and release the wrapping water, but also make the tofu brain spread evenly on the wrapping cloth, and the quality of the products made is close, which can avoid uneven thickness and more gaps.
6. wrap it. Spread the wrapping cloth on the grid first, and then add the bean curd onto the wrapping cloth, so that the bean curd should be spread evenly layer by layer, which can be a few millimeters higher than the grid. The quantity should be determined according to the thickness of the dried bean curd, but the thickness of each batch should be consistent. Then tie the cloth tightly, press and shape it, remove the cloth after 1 hour, cut the dried tofu with a knife according to the grid print, and soak it in clean water for about 30 minutes to take it out.
7. soak. First, put 500 grams of refined salt into 3 kilograms of clear water and mix well, then put the dried bean curd in a dry salt water tank, soak it for half a day, then take it out and drain the water. Pour 7kg of clean water into a pot, and put100g of refined salt, diced ginger, cinnamon (packed in gauze), soy sauce, chives and monosodium glutamate to make brine.
8. Boil dry. Bring the prepared brine back to the pot, add dried bean curd, and cook for about 30 minutes. Take a dried bean curd for observation. If it is brownish red in color and delicious, take it out.
